I would look up someone who builds TZ250 race bikes. There are a few...very few people who do work on vintage race bikes who I'm sure can help out. But I'm also sure the waiting line is probably long.
Dig into some TZ250 specific sites, and you can probably find your guy.

I tend to use Athena gaskets. Got a clutch cover one on right now. Good quality. Either PJME or you could see if there are any on Ebay. PJME have them for under £10.00.
Don't use sealant but do make sure the mating surfaces are really clean. Some on other 2 stroke forums advocate giving the gasket a wipe with something like WD40 to help with removal later if needed. Not tried this yet.

I see the Sunstar's now. Not too bad at $180 USD each I guess. Shipping is $88.44! Ooof...those tarrifs

Quote from: Rasher on April 28, 2026, 08:35:00 PMLots of new rotors are the "wave" style with a wavy outer edge - instead of a traditional smooth circular outer edge.Quote from: RockyFranco on April 28, 2026, 03:49:27 PMi don't like the shape of those rotors...
I assumed they are all round, what shape are these?
Looks fine on a current sport bike, but kinda odd on anything older.

If it's like my 3xv and I'm pretty sure it is.
You have to split the cases because there is a grove. That runs around the center of the seal that fits into the cases.

Hi everyone,
The left‑hand crank seal is leaking on my 3ma— more of a weep than a full leak. I've asked around locally and I'm getting mixed answers. Some people say the seal can simply be pulled out and replaced, while others insist it requires a full engine strip‑down.
Can anyone shed more light on what's actually involved?
